Bike Trunk Bags

Need more space but not a wobbling bike? Attach a durable and spacious trunk bag to your bicycle and make your commuting easy. Our bicycle trunk bags are designed like large baskets, but have the functionality of a carry-on bag. Usually, you can only mount these trunk bags to the rear rack, but we wanted to give you more value. So we introduced bags with 4-in-1 functionality. You can attach our bike bags to your rear rack, handlebar, basket, and sides. With easy-to-use tack straps and a shoulder straps, you can attach these trunk bags to your cycle within seconds. Get one right now, to make your bicycle commuting a lot easier. 

*Receive 2 FREE Tack Straps to upgrade your handlebar straps with any new Alpha, Dayliner or Dayliner Mini purchase.

Durable and Spacious Bike Trunk Bags

A strong trunk bag is a good trunk bag. That's why we use durable and waterproof materials like TPU backed 600D polyester to create your dream trunk bag. With a roll-top closure, you can bet it's safe from the elements. Each trunk bag also comes with a flourescent waterproof rain cover that guarantees the protection of your items in even the heaviest of downpours.

Our Dayliner Trunk Bags have 20 liters of expandable storage space. You can use this space to store all your essentials on a short trip to town, or on a small tour around the weekend. Due to the versatility of our bags, you can use them easily with other accessories and bike panniers, for more space and security.

How to Attach a Trunk Bag

Our exclusive Two Wheel Gear Dayliner has heavy-duty velcro straps, slide attachments, handlebar mounts, and a stem stabilizer for easy attachment to your bike. 

For front rack attachment, place it in against your handlebar and secure the bag using the buckles and tighten the stem cords.
For rear mounting, place it on the rear rack of your bike. Secure the bag using the velcro straps, by passing them under the rack.
For the bike basket, just place it in the basket and secure it using the stem cords.

Because of its universal design, our trunk bag can latch onto most most standard racks. Get your TWG Trunk Bag and make your everyday life much easier. Enjoy spacious trunk storage, peerless security for your precious items, free shipping and a 2-year warranty, all at an affordable price.
